Land use and land cover change has become the core region of land sciences, earth systematic sciences, global environmental change and sustainable development. The fundamental objective of such research is to realize the effective management and sustainable use of land resource. They are not only the fundamental basis to solve the problem of resource and environment, but also the essential predomination for the economic growth and the process of regional sustainable development. Taking major related research plans and projects both in China and abroad in recent years for reference, this paper summarized the up to date international progress of several regions in the land science, such as land use and land cover change, systematic analysis and evaluation of land resources, land quality indicators system, impacts on ecological environment and the sustainable land use.
